At the same meeting, the committee, in continuation of the 

 subject as presented in the Report of last year, pp. 103-114, 

 submitted the following 



REPORT 



ON ROOT CROPS. 



Your Committee have found it necessary in order fully to 

 consider the economy and the necessity of the root crop to the 

 farmers of Massachusetts to present by comparative tables the 

 commonly accepted facts as to the nutritive value of the various 

 crops which are generally cultivated by our farmers. We have 

 gathered from the sources of knowledge open to us many facts 

 which seem to carry evidence of their importance to every ob- 

 serving mind, and which have been confirmed in our own expe- 

 rience or in the experience of farmers personally known to us. 



Carrots, Mangolds, Swede Turnips. — Many of the state- 

 ments in circulation of an immense yield of these crops, and of 

 wonderful results in feeding the same are known to be unreli- 

 able. The average product and value of these crops must be 

 taken if we would prudently consider the expediency of enter- 

 ing upon their cultivation.
